There is a good DIY thread
Here to install the front carrier bushings.
I did the Cusco fronts and torque solutions rear. Cusco requires both inner and outer front OEM bushing to be removed. The torque solutions from information available suggest just the OEM outter is swapped.
I had a short shifter installed with this combo and ended up removing it going back to OEM shifter. It was TOO tight if that's even possible, and the shifter rattled like crazy.
Thread covers everything pretty well. It's a tight job with a lot of hand snaking, it can be a PITA to realign the front to get the pins back in; patience is key. You will likely end up staring at the underside of your car at one point questioning your life decisions.
Whiteline trans insert also makes the shifter feel more solid. Cheap easy mod. TRD trans mount has similar net effect without the added NVH.
